Description
Technical field
The utility model relates to alarm device, particularly relates to a kind of earthquake warning device.
Background technology
The Working Life social stability of earthquake to people caused extreme influence in order, and many earthquakes occur in the late into the night or morning, and owing to being taken by surprise, this can make wrecked number greatly increase.
Why earthquake at night can cause so large injures and deaths, sums up and has following two reasons: once being that people are not awake wrecked in one's sleep, or awake but consciousness is also among fuzzy, has missed the best opportunity of escaping; Two is seismic power failures, and people can not promptly look for best-effort path in the dark.
On geography class, we learned, and earthquake can be divided into three types by circulation way: compressional wave, shear wave and ground roll.
Compressional wave is translatory wave (also known as P ripple), and the velocity of propagation in the earth's crust is 5.5-7 thousand meter per second, arrives earthquake centre at first, and it makes ground that up-down vibration occur, and destructiveness is more weak.Shear wave is shearing wave (also known as S ripple), and the velocity of propagation in the earth's crust is 3.2-4.0 thousand meter per second, and second arrives earthquake centre, and it makes generation all around, ground shake, and destructiveness is stronger.Ground roll (also known as L ripple), be the mixed recharge being excited generation by compressional wave and shear wave after meeting in earth's surface, wavelength is large, amplitude is strong, can only propagate along ground surface, is the principal element causing buildings strongly to destroy.
From these describe, I finds, the compressional wave of earthquake arrives ground early, and destructiveness is more weak; And during shear wave arrival, often started to produce larger destruction to buildings, this alarm is somewhat late.Earthquake Alarm kind at present on the market for family is many, but great majority are transverse vibration induction, therefore, the how information knowing compressional wave as early as possible, perception earthquake more early is also reported to the police, thus wins more valuable escape time for people, is the emphasis of the utility model discussion.
Utility model content
Based on this, be necessary, for prior art problem, to provide a kind of earthquake alarming instrument, while this earthquake alarming instrument electric conductivity is stable, its structure is simple.
For solving prior art problem, the utility model adopts following technical scheme: a kind of earthquake warning device, include induction trigger device, hummer, power supply, described induction trigger device is made up of an induction support, pendulum, induction support is provided with a support, support is provided with upper connecting rod, lower connecting rod, and the upper connecting rod other end connects upper copper band, the lower connecting rod other end connects lower copper band, and support connecting electrode A, upper copper band, lower copper band, upper connecting rod, lower connecting rod are electrically connected with support;
Pendulum is provided with one and leads cycloid, and lead cycloid lower end and connect swing ball, swing ball falls in lower copper band, and lead cycloid upper end and be connected with spring through upper copper band, the spring other end is connected with peg, peg connecting electrode B.Swing ball, cycloid, spring are electrically connected with peg.
Further: the diameter of described upper copper band is less than the diameter of lower copper band.
Further: described upper connecting rod, lower connecting rod and support are for being flexibly connected.
The beneficial effects of the utility model are:
1, compared with the common seismograph that only can detect shear wave, horizontal stroke, longitudinal wave earthquake induction alarm device to the reaction of earthquake more early, can win the escape time of more preciousnesses;
2, this apparatus structure is simple, and production cost is low, applied widely.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
For feature of the present utility model, technological means and the specific purposes reached, function can be understood further, below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
Referring to Fig. 1, the utility model discloses a kind of earthquake warning device, forming by being with the emergency light of independent current source, induction trigger device, hummer, relay switch.Wherein said induction trigger device is made up of an induction support, pendulum two parts, induction support is provided with a support 1, support 1 is provided with upper connecting rod 4, lower connecting rod 5, connecting link 4, lower connecting rod 5 are flexibly connected with support 1, and the position of upper connecting rod 4, lower connecting rod 5 can adjust according to the actual requirements.
Upper connecting rod 4 other end connects upper copper band 2, lower connecting rod 5 other end connects lower copper band 3, and the diameter of upper copper band 2 is less than the diameter of lower copper band 3.Support 1 connecting electrode A, upper copper band 2, lower copper band 3, upper connecting rod 4, lower connecting rod 5 are electrically connected with support 1.So far, respond to Bracket setting to complete.
Pendulum is provided with one and leads cycloid 6, and lead cycloid 6 lower end and connect swing ball 7, swing ball 7 falls in lower copper band 3, and lead cycloid 6 upper end and be connected with spring 8 through upper copper band 2, spring 8 other end is connected with peg 9, peg 9 one end connecting electrode B.Peg 9 is electric conductor, and swing ball 7, cycloid 6, spring 8 are electrically connected with peg 9.
When earthquake occurs, compressional wave makes building vertical tremor, and now, due to linking springs 8 above cycloid 6, swing ball 7 is meeting vertical tremor under the effect of self gravitation, thus touches the lower copper band 3 be positioned at below swing ball 7, connects circuit triggers and reports to the police; As seismic intensity is little, compressional wave is strong not, then when shear wave arrives, swing ball 7 swings, and cycloid 6 touches the upper copper band 2 be positioned at above swing ball, thus connects circuit triggers warning.
In sum, this earthquake alarm device has following features:
1, compared with the common seismograph that only can detect shear wave, horizontal stroke, longitudinal wave earthquake induction alarm device to the reaction of earthquake more early, can win the escape time of more preciousnesses.
2, horizontal stroke, longitudinal wave earthquake induction alarm device and emergency light are firmly fixed on wall, according to the actual conditions of residing environment, by regulating the copper band on support 1, the sensitivity of touching switch can be changed simultaneously, make earthquake alarm more accurate and effective, the situation of wrong report can be greatly reduced simultaneously.In addition, by selecting suitable spring 8 and swing ball 7, the susceptibility of this device to longitudinally vibrations can greatly be improved.
3, this apparatus structure is simple, and production cost is low, applied widely.Comprise the places such as ordinary residence, school, hospital, mall, hotel, factory, government bodies all applicable.
The above embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
